The average speed, in [tex]$km / h$[/tex], for a journey of 50000 km in 30 min will be:
Answer (2)
Convert the time from minutes to hours: 30 minutes = 0.5 hours .
Use the formula for average speed: Average speed = Total time Total distance .
Substitute the given values: Average speed = 0.5 hours 50000 km .
Calculate the average speed: Average speed = 100000 km/h . The average speed is 100000 .
Explanation
Understanding the Problem We are given a journey of 50000 km that takes 30 minutes. We need to find the average speed in km/h.
Converting Time to Hours First, we need to convert the time from minutes to hours. Since there are 60 minutes in an hour, 30 minutes is equal to 60 30 = 0.5 hours.
Applying the Formula Now, we can use the formula for average speed: Average speed = Total distance / Total time. In this case, the total distance is 50000 km and the total time is 0.5 hours.
Calculating Average Speed So, the average speed is 0.5 50000 = 100000 km/h.
Final Answer Therefore, the average speed for the journey is 100000 km/h.
Examples
Understanding average speed is crucial in everyday scenarios, such as planning a road trip. If you know the distance you need to travel and the time you have, you can calculate the average speed required to reach your destination on time. For example, if you need to travel 300 km in 3 hours, the average speed you need to maintain is 3 300 = 100 km/h. This helps in managing your travel efficiently and safely.
The average speed for a journey of 50000 km in 30 minutes is 100000 km/h. This is calculated by converting 30 minutes to hours and using the formula for average speed. Therefore, the average speed is 100000 km/h.
